I got an old Meinberg GPS, with an analogue integrating single-channel
receiver, and put at a friends appartment. Still works great, after me
convincing it about a new location. It has two time-tagging inputs, so
you can get UTC time-stamps with 100 ns resolution of the serial port.
With a good trigger and then a serial adapter... you got some cool
time-stamping good enough for the purpose I guess.:)

At 3000fps, even a one foot screen spacing would give good results
with 100nS! On top of that you'd know the exact time of day, and
location!
We built some time measurement hardware at work with many channels
running at 5nS resolution. Since a lot of us are into shooting sports,
we did the math then. We basically figured figured that 5nS would be
overkill for a chronograph. Fun, but overkill. :)
